I once had a dream that I was going to a sex con. If any of you have ever been to an anime convention, just imagine that with LOADS of hentai. Also, I was going with my girlfriend, who was a combination of Stacky and The Magnificent Milkmaid. So we go into the con, shop the Dealer's Room for a while and promptly have sex later on. Then we go to one of the events, where we can simply sit and observe famous hentai stars (Yumiko, any Monzetsu character) having sex. However, we actually watch from a small crack in the adjacent hallway.
BUT THEN a huge mass of Shaolin Monks come bursting in and arrest us, claiming that voyeurism is against their religion. So they arrest all of us and force us to enlist in Starfleet.
I swear to god, I am not making this up.
Anyway, after the sun blows up, wiping out all life on earth, I wake up back at Sexcon. I pass a girl I know in the halls, but oddly enough, nothing ever comes of it. Personally, I find that odd. Anyway, everyone is now leaving the con to get on the boat to go to the mainland.

Oh yeah, did I mention Sexcon is located on a volcanic island? Cause it is. Anyway, my parents come, somehow drag me by the arm around a mile and a half through black, barren environment onto the boat, where I promptly start singing the "I'm On a Boat" accapella version. However, I manage to break free and teleport back to the con, desperately looking for The Magnificent Stacky.
However, what I find is a gigantic building that looks a lot like the parthenon, except all Egyptian like. So I go in and search the now cathedral-like halls. But I don't find her and walk out.
But apparently even God isn't fond of me, as he starts sending huge T-Rexes, Velociraptors, and roaches at me. Not Radroaches, mind you, just regular roaches.
And so then, I suddenly turn into my Fallout 3 character and start using VATS to blow the shit out the assorted dinosaurs. Then, on the long trek to the boat, I turn into King Kong (From the 2005 VG) and kill some more T-rexes that ambush me.
And then I wake up. At first I cry, but then I laugh and realize that I'm going to have something excellent to tell the internet later.
Oh wait, this was for weirdest THINGS we've ever done in our sleep? Oh. Um... I once levitated. Or at least I thought I was levitating. I was actually sleeping on our pool cover.
